Road widening is the most common way of reconstruction and expansion, but the widening can cause cracking and even collapse of the new and old roadbed joint and the old roadbed, and causes great driving safety and economic loss. Therefore, deformation and settlement deformation possibly occurring in the service period of the road subgrade need to be monitored, most of the existing monitoring sensors are distributed in a point shape, so that the cost is high, and distributed testing is not supported.
The novel intelligent machine-sensitive belt is a conductive polymer material, has the functions of conductivity and intelligent detection of resistance deformation (sensitivity to strain), and is suitable for an intelligent early warning and detecting system for settlement and deformation of highway subgrades. The sensor type plastic geosynthetic material is the first sensing type plastic geosynthetic material in the world, can realize distributed monitoring of internal deformation of a soil body, and is large in range (the strain range reaches 10%), good in durability and low in cost. The mechanical sensitive belt breaks through the technical problems that the internal tensile deformation of the soil body and the deformation of reinforced soil reinforcement materials are difficult to monitor. The smart geobelt has strong tension-sensitive effect, the conductivity has strong linear sensitivity to deformation within 7 percent of deformation, and the deformation value can be obtained by testing the resistance change; the strength is high, and the strength of a machine-sensitive belt with the thickness of 1.5mm can reach more than 25 kN/m. For laying the intelligent machine-sensitive tape with the topic of 'safety detection for geotechnical engineering' with the application number of 202021146699.X, a safe and reliable standard construction method is needed.
